Beyonce Supports Jay-Z at His Barclays Center Show

Beyonce proudly watched her hubby perform at the grand opening of the Barclays Center in Brooklyn, New York. The 31-year-old mother to Blue Ivy, 8 months, enjoyed the nearly two hour show from the D'USSE VIP Lounge. She was "front and center," a source tells Us Weekly. "She went crazy singing and dancing to every song."

Jay-Z, 42, (real name: Shawn Carter) performed his hits like "99 Problems," "Run This Town" and "Empire State of Mind."

Beyonce wore a tight black v-neck top, gold belt and gold bracelets. During "Dirt Off Your Shoulder," Beyonce had some fun by grabbing a flashlight from a security guard and shining it on people in the crowd. "She was having fun a playing with people," a witness tells Us.

And Jay-Z was having a good time too. The rapper, who grew up in the housing projects of Brooklyn, welcomed the crowd to his "house" and said, "I've performed in a lot of places but nothing feels like tonight." A source tells Us, "He was really emotional during the show."
